Project Mikoto + FCO

Hi, so I got back into playing New vegas moded. I plan on retaking my Black Dynamite playthrough but I am having an issue with making the custom races added by FCO and Dragbody's overhaul mods being able to use the hair included in Project Mikoto.

I found an "Auto patcher" but that one seems to have fucked up the Breeze bodies and the Dragbody's Overhaul heads are getting rendered without eyes or just not rendered at all.

I keep reading that there is a way to fix this with FNVEDIT but everyone that brings it up doesn't go int odetail and it seems to be some common knowledge whose explanation is lost to time because I can't find any videos on how to do it.
